My dog attacked my ex boyfriends dog and i think he hates my dog now

Hi everyone, I (17F) and my ex boyfriend, (18F) both have dogs. For context my ex boyfriend and i are on good terms and still communicate with each other on a daily basis. My dog is a female english mastiff, while his dog is a male english springer spaniel.

Last night my ex boyfriend was walking his dog and stopped at my house to pick up some stuff. I was waiting on my porch for him and as i was going back inside my dog (lola) ended up pushing past me to get to ex’s dog (odi.) I tried to grab lola as she was running out the door but i am 5’3 and i’m not very strong compared to lola. So unfortunately i could not stop her and she latched on to odi and dragged him down the porch steps.

My ex boyfriend and i both tried to get in the way and break up the fight but we could not keep lola down as she is a huge dog. Two of my neighbours ended up running over to help. (Bless them.) one of them helped hold lola down while the other one took odi away.

All of the yelling and yelps woke my dad up and he came outside clearly angry because he had work the next morning and it was about 10pm. My dad was obviously upset because we have been sued before because lola is aggressive with other dogs.

(I’ll make this part short but when we were at a dog park with lola, one of the other dog owners brought a dog toy which isn’t allowed. Lola saw it and ran to get it and the woman tried to grab the toy first and lola ended up nipping her trying to get the toy.)

Anyways our biggest fear is having to put her down because she really is a sweetheart. she just had problems with other dogs. We have two cats and she cuddles with them and gets along with them great. she pretends to bite them but it’s never hard and she’s very gentle with them so we aren’t sure what her issue is with other dogs.

I’m sorry i’m getting off track but after all of that happened my ex boyfriend has been quite annoyed with me and told me he’s not sure if he hates lola or not because lola did end up biting him as well when he was tryna to get odi out of lola’s mouth.

My question is, how can my ex boyfriend and i move on from this? we didn’t work in a relationship but we are great as friends and i want him to not have hatred for lola if that makes sense. my relationship with my ex right now is quite tense and im not sure what to say or do to help us move on from this.
